Title: Friction false-twisting apparatus
IPC: D02G1/08
Filed: 1980-09-17
Abstract: Friction false-twisting apparatus for selectively producing Z-twist or S- twist yarn and comprises at least three sets (4, 5, 6) of friction discs, each set having at least one friction disc mounted on a respective spindle and overlapping the discs of the remaining sets. The spindles are arranged to be driven in the same yet changeable rotational direction and their axes are in triangular formation. To change from one type of twist to the other, the direction of rotation of all sets is reversed. Additionally the two pivotable sets (4, 5) are pivoted out of their operative positions into positions (as shown) in which none of the discs overlap, to interchange said two sets with the effect that when they are pivoted back into their operative positions all the discs will overlap again but in another order and sequence. Said two sets, in a preferred embodiment, are rotatably arranged in a respective one of two pivotable supports (2, 3) and instead of interchanging the sets by themselves the supports are interchanged with the same effect. <IMAGE>

Title: Method and apparatus for reducing oscillation of running strip
IPC: B65H23/02
Filed: 1980-12-22
Abstract: In a continuous galvanizing line, oscillation of a steel strip 10 withdrawn from a molten zinc metal bath (12) is reduced by liquid-cooled anti-vibration magnets (34, 36, 38, 40) disposed in the vicinity of the respective side edges of the steel strip (10). The magnets cause tension in the strip in the direction of the strip width and amplitude of the oscillation of the strip perpendicular to the strip surfaces is reduced. Also, by magnetic force of the magnet, bending of the running strip is cured and a uniform coating is obtained. The gap between the magnets and the strip side edge is automatically controlled using a motor 48, actuated by detecting signals derived from sensors scanning the gap. Such anti-vibration magnets can also reduce oscillation in other strip processing lines, and an application to a strip inspection line is disclosed. <IMAGE>

Title: Method for feeding pieces of timber into a timber processing machine and arrangement for carrying out the method
IPC: B27B1/00
Filed: 1981-02-02
Abstract: The method and arrangement work according to the principle that the contours in the longitudinal direction of the piece of timber (10A) are first measured by measuring devices (22, 23) which exert minimal pressure on the piece of timber, after which the piece of timber is advanced to at least one control device (32, 33) which is arranged immediately adjacent to the processing machine and acts laterally upon the piece of timber with a considerably larger alignment force. Measurement signals from measuring devices are processed in a known manner in a computer (D) from which the order signals are sent to the control unit with a determined delay. The control device operates both as an alignment device, by aligning the piece of timber to the necessary feed attitude calculated in the computer, and as a control device in the stricter sense of the term by controlling the piece of timber while it is being fed into the processing machine. The control devices may be positioned to one side of the measuring devices. <IMAGE>

Title: Flaw detection method
Inventor: CROWE GEORGE VICTOR
IPC: G01N27/82
Filed: 1983-03-24
Abstract: Surface flaws in a magnetisable object are detected and recorded for subsequent reference by applying to the flawed surface a sheet of material which, when the object is magnetised, becomes magnetised itself but only in those regions which overlie the or each surface flaw and which can be removed from the test surface without destroying by such removal the flaw pattern record so obtained. In one embodiment the sheet of material is obtained by spraying as an aerosol a solution of ferromagnetic particles, solvents, base lacquers and propellants which then dries to a skin which can subsequently be peeled off the test surface. In another embodiment the sheet is a sheet of magnetic recording tape which when removed from the surface is developed by applying a suitable magnetic ink to it. In the latter embodiment the magnetic ink may be applied as an aerosol spray which then dries by evaporation.

Patent GB-2151868-A (GB)
Title: Optical amplifiers
Inventor: BYRON KEVIN CHRISTOPHER
IPC: H04B10/29
Filed: 1983-12-16
Abstract: @ Use is made of stimulated Raman emission to induce gain in an optical signal (13) of a first wavelength. The optical signal (13) and a pump signal (14) are synchronously coupled to a length of optical fibre (15). The pump signal is at a second wavelength. The first wavelength corresponds to one Stokes shift from the pump signal. The pump signal is generated by a semiconductor laser (11) and thus only relatively low pump powers are involved in comparison with the conventional use of YAG lasers as the pumps, however significant gain is achieved despite the low pump powers. Preferably the optical fibre (15) has a high Raman cross-section and a low transmission loss, for example GeO<sub>2</sub> doped SiO<sub>2</sub> or pure Ge0<sub>2</sub>.
